Interaction Effects on the Magneto-optical Response of Magnetoplasmonic Dimers

The effect that dipole-dipole interactions have on the magneto-optical (MO) properties of magnetoplasmonic dimers is theoretically studied. The specific plasmonic versus magnetoplasmonic nature of the dimer's metallic components and their specific location within the dimer plays a crucial role on the determination of these properties. We find that it is possible to generate an induced MO activity in a purely plasmonic component, even larger than that of the MO one, therefore dominating the overall MO spectral dependence of the system. Adequate stacking of these components may allow obtaining, for specific spectral regions, larger MO activities in systems with reduced amount of MO metal and therefore with lower optical losses. Theoretical results are contrasted and confirmed with experiments for selected structures

Non-line-of-sight transient rendering

The capture and analysis of light in flight, or light in transient state, has enabled applications such as range imaging, reflectance estimation and especially non-line-of-sight (NLOS) imaging. For this last case, hidden geometry can be reconstructed using time-resolved measurements of indirect diffuse light emitted by a laser. Transient rendering is a key tool for developing such new applications, significantly more challenging than its steady-state counterpart. In this work, we introduce a set of simple yet effective subpath sampling techniques targeting transient light transport simulation in occluded scenes. We analyze the usual capture setups of NLOS scenes, where both the camera and light sources are focused on particular points in the scene. Also, the hidden geometry can be difficult to sample using conventional techniques. We leverage that configuration to reduce the integration path space. We implement our techniques in a modified version of Mitsuba 2 adapted for transient light transport, allowing us to support parallelization, polarization, and differentiable rendering. © 2022 The Author(s

Development and Initial testing of a Virtual Laboratory for the Build-up and Testing of Microgrid Management Algorithms

In a bid of facilitating the increasing penetration of intermittent and random renewable energies, microgrids along with their management algorithms are becoming crucial assets. To prove their effectiveness, these algorithms need to be tested in real environments and/or laboratories, which can be very difficult in many cases, especially at the initial development stages. To solve this issue, this article proposes the use of a laboratory digital twin, i.e., a virtual laboratory with a behaviour that is similar to that of real installations, aimed at facilitating the development, testing and debugging of microgrids management algorithms. The proposed solution is demonstrated to be safe and complete when it comes to test these algorithms.Acknowledgement This publication is part of the Sistemas energéticos aislados 100% renovables ENERISLA (exp.

Feasibility of Vermicomposting of Spent Coffee Grounds and Silverskin from Coffee Industries: A Laboratory Study

In the coffee industry, several by-products are generated during the production and consumption of coffee and represent an important waste from an environmental viewpoint. For improving the knowledge about this issue, a laboratory vermicomposting study of coffee silverskin (CS) and spent coffee grounds (SCG) spiked with mature horse manure (HM) in different proportions and using earthworm Eisenia andrei was carried out. The 60-day study focused on biological parameters such as total biomass gain, growth rate, cocoon production, and mortality. This study also investigated whether the vermicompost obtained could be useful and lacked toxicity through a seed germination test using hybrid wheat seeds. Results showed a disparity depending on the type of residue and the mixture used. Best options were those treatments with a medium–low amount of residue; 25% for SCG and 25% or 50% for CS. In addition, lack of toxicity was confirmed in all treatments. In conclusion, it is possible to carry out a vermicomposting of SCG and CS with some specific features.This research was funded by Government of Navarre and European Regional Development Fund (ERDF) grant number VERMICOMPOSTAJE 4.0—VERMIOT (0011-1365-2019-000110), research project.

Mudanças no perfil funcional de pacientes con patologia psiquiátrica resistente submetidos a neurocirurgia funcional estereotáxica

Con el objetivo de evaluar los resultados de la Neurocirugía Funcional Estereotáctica (NFE) sobre el perfil funcional de los pacientes diagnosticados con Patología Psiquiátrica Resistente (PPR), se realizó un diseño pre/post tratamiento. 13 pacientes fueron evaluados ( = 31 ± 8 años): siete mujeres diagnosticadas con algún Trastorno de la Conducta Alimentaria Resistente (TCAR); tres mujeres diagnosticadas con Trastornos Resistentes Obsesivo Compulsivo y Depresivo (TOC y DR) y tres pacientes (dos mujeres y un hombre) diagnosticados con Depresión Resistente (DR). A estos pacientes se les aplicó la Escala de funcionamiento del paciente Eje K, la cual consta de siete subescalas, y una Escala de Evaluación de la Actividad Global (EAG) antes del tratamiento y después de éste (seis meses posteriores a la NFE). Todos los grupos diagnósticos y el total de los pacientes evaluados presentaron cambios clínicos positivos; sin embargo, sólo el grupo de TCAR mostró importantes cambios clínicos de mejoría en el perfil de funcionamiento, siendo esta diferencia estadísticamente significativa (pre Md = 56; post Md = 84; z= - 2.36, p <0.05). Con la evidencia obtenida se observó que la NFE representa una opción terapéutica emergente efectiva orientada a disminuir el sufrimiento de los pacientes con PPR, así como a mejorar el nivel de funcionamiento global y por ende su calidad de vida. Todos los pacientes del estudio presentaban una condición de resistencia a tratamientos convencionales indicados, la cual había sido documentada por un equipo interdisciplinario experto.Con o objetivo de avaliar os resultados da Neurocirurgía Funcional Estereotáxica (NFE) sobre o perfil funcional dos pacientes diagnosticados com Patologia Psiquiátrica Resistente (PPR), realizou-se um desenho pré/pós tratamento. 13 pacientes foram avaliados ( = 31 ± 8 anos): sete mulheres diagnosticadas com algum Transtorno da Conduta Alimentar Resistente (TCAR); três mulheres diagnosticadas com Transtornos Resistentes Obsessivo Compulsivo e Depressivo (TOC e DR) e três pacientes (duas mulheres e um homem) diagnosticados com Depressão Resistente (DR). A estes pacientes foi aplicada a Escala de funcionamento do paciente Eixo K, a qual consta de sete sub-escalas, e uma Escala de Avaliação da Atividade Global (EAG) antes do tratamento e depois dele (seis meses posteriores à NFE).

Thirteen patients were assessed ( = 31 ± 8 years): seven women diagnosed with some type of Resistant Eating Disorder (RED); three women diagnosed with Resistant Obsessive Compulsive Disorder and Resistant Depression (TOC and RD), and three patients (two women and one man) diagnosed with Resistant Depression (RD). The Patient's Functioning Scale, axis K, consisting of seven subscales, and the Assessment of Global Activity Scale (AGAS) were applied before and after treatment (6 months after FSN). All diagnostic groups and all the patients assessed showed positive clinical changes. However, only the RED group showed important clinical improvement in the performance profile with a statistically significant difference (pre Md = 56, Md = 84 post , z = - 2.36, p <0.05). With the evidence obtained it was noted that SFN represents an effective therapeutic option aimed at reducing the suffering of patients with RPP and improve their overall level of functioning and therefore their quality of life. All patients in the study had a condition indicating resistance to conventional treatments which had been documented by an expert multidisciplinary team

Raman and infrared spectroscopy of Sr2B′UO6 (B′ = Ni; Co) double perovskites

Temperature dependent normal modes and lattice thermal expansion of Sr 2B′UO6 (B′ = Ni, Co) double perovskites were investigated by Raman/infrared spectroscopies and synchrotron X-ray diffraction, respectively. Monoclinic crystal structures with space group P21/n were confirmed for both compounds, with no clear structural phase transition between 10 and 400 K. As predicted for this structure, the first-order Raman and infrared spectra show a plethora of active modes. In addition, the Raman spectra reveal an enhancement of the integrated area of an oxygen stretching mode, which is also observed in higher-order Raman modes, and an anomalous softening of ∼1 cm-1 upon cooling below T* ∼ 300 K. In contrast, the infrared spectra show conventional temperature dependence. The band profile phonon anomalies are possibly related to an unspecified electronic property of Sr2B′UO6 (B′ = Ni, Co).Centro de Química Inorgánic

Estrogen and progesterone up-regulate glucose transporter expression in ZR-75-1 human breast cancer cells

Indexación: Scopus.Breast cancer incidence increases in women receiving combined estrogen and progesterone therapy. Breast tumors show increased expression of the glucose transporter GLUT1. We determined the effect of these hormones on GLUT1-4 expression and deoxyglucose transport in ZR-75-1 breast cancer cells. Immunoblotting, immunocytochemistry, flow cytometry, and RT-PCR showed that GLUT1 expression is up-regulated by progesterone and, to a greater degree, combined therapy. GLUT2 expression is unaffected by hormonal treatment. GLUT3 protein and RNA is up-regulated by progesterone and combined therapy, and GLUT4 protein expression is up-regulated by all hormonal treatments. Deoxyglucose transport studies revealed the presence of three transport components with characteristics corresponding to GLUT1/4, GLUT2, and GLUT3. 17β-Estradiol produced a slight increase in transport at the Michaelis constant (Km) corresponding to GLUT3. Progesterone produced a small increase in transport at the Km corresponding to GLUT1/4, and combined 17β-estradiol and progesterone produced a small increase in transport at the Km corresponding to GLUT3 and a large increase in transport at the Km corresponding to GLUT1/4. This indicates that 17β-estradiol and progesterone differentially regulate GLUT1-4 expression and that these changes correlate to changes in glucose uptake. We postulate that combined hormone replacement therapy provides a survival advantage to developing ZR-75 breast cancer cells.https://academic.oup.com/endo/article/144/10/4527/250236
